3 claims. (ol. 98487) f This invention relates to window ventilators so constructed as to be adapted to be installed in the frame of a window sash or in a door.

The principal object of the invention is the production of a ventilator of simplicity of construction, of cheapness to manufacture, of few parts and one which may be readily installed in any window frame or door of standard construction and at a minimum of expense.

Further objects of the invention are the production of a window ventilator having the characteristics specified above and s o constructed as to be manipulated to avoid excessive drafts and to be capable of adjustment to admit air varying in quantities while the window sash itself is closed or the door .is closed.

To the above ends my invention consists in the novel window ventilator and the combination of parts thereof hereinafter more particularly described and then specified in the claims and from which description other and further objects of the invention will be manifest v In the accompanyingdrawing illustrating the practical embodiment of the invention:

Fig. 1 is a front elevation (partly broken away) n of a window Ventilator constructed in accordance Fig. 5 is a front elevation.. (partly brokenaway) of a modification.

Referring in detail to the several figures of the drawing: l, Y

I prefer to construct my improved windowr ventilator of sheet metal. An outer rectangularshaped frame of the device is indicated at II), said frame being preferably provided with upper and lower anges I I and I2 respectively and with side flangesIB. A rectangular-shaped opening is cut in the window frame or in the door I3' of the proper size to receive the frame, the opening preferably being cut at the bottom of the frame of the window or at the bottom of the door. The frame is then slipped upwardly into the opening so that the anges thereon will closely engage the front and rear surfaces of the window frame or door, as the case may be, and as indicated in Fig. 4, and it is held in position in any desirable manner. The space at thebottom of the opening in the frame of the Window or in the door is then filled by the block of wood I4 lwhich is slipped into position intermediate the -lower anges I2 of the frame and secured in position in any convenient manner. Obviously, and if so desired, the lower flanges I2 may be dispensed with 5 in which case the construction would be such that the lower wall of the frame would lie flush with the lower outer surface of the window frame or door.

The body of the ventilator comprises preferably 10 shaped openings 2 I. 20

Closure Vslide members arev indicated at 22.

These are adaptedto slide on the track members I5 and are similarly provided with rectangularshaped openings 23 of the same size as the openings 2| in track members I5 and are adapted to be brought into registry therewith. The side walls of the frame II) of the ventilator act as stops -tovlimit the horizontal movement of the slide members 22 on the track members I5.

Each of the closure slidemembers 22 is pro- 3Q terminating in an operating knob 29. Obviously, 40N

movement of the operating knob 2S to the left orright will affect the movement of the closure slide members 22 to bring the openings 23 into registry with the openings 2l of the track members I5 or to close the openings in said track 45 members. Any suitable means for retaining the closure slide members into sliding .engagement with the track members may be employed such for such instance, as lugs or projections or a flange onthe horizontal cross bars I'I and I8 or either 50 of them.

The quantity of air which it is desired to admit into a room or other enclosure from the outside may be varied, as is manifest by `regulating the position of the closure members 22 with respect 55 to the track members I5 to vary the size of the air admission openings formed by the openings 2| and 23. Air from the outside flows in the direction of the arrows as indicated in Fig. 4. The upwardly inclined walls i6 are provided to prevent the admission of the elements, such as rain, directly into the room, the inclined walls being formed as an integral part of the body of the device, as has been explained, and being embodied directly within the frame of the ventilator.

To further insure a complete closing of the ventilator in order to prevent leakage of air even when the closure slide members 22 are in closed position and to enhance the appearance of the ventilator and hide the interior construction thereof from view, I provide shutters 30 hingedly mounted on the vertical front flanges of the frame or otherwise hinged to the frame. These are adapted to close the spaces intermediate the horizontal cross bars I8.

Each shutter 3i! is provided with an outwardly extending projection or lug 3i and said projections are pivotally connected together by means of an operating arm 32 so that manipulation of said operating arm operates said shutters simultaneously into open, intermediate or closed psition. When the shutters are in inclined position they1 act as baffles to deflect the air upwardly instead of having it flow directly into the room. The operating arm 32 may also be provided with notches 33 for receiving the edge of a shutter when in open position and acting as a stop to prevent further downward movement of the shuttei'.

The modiication illustrated in Fig. shows in elevation (looking at the ventilator from the room) a more simple form of the device. In said modication I dispense with the operating means for the closure slide members illustrated in Figs. l and 2 and in lieu thereof provide an operating finger piece 34 having extensions (not shown) secured in any manner to the slide members so that movement to the right or left of said finger piece will simultaneously move all of said slide members in the same direction. In the modification I also prefer to dispense With the shutters 30 previously described.

Various modications may be resorted to without departing from the spirit of the invention as set forth in the appended claims. It will also be obvious from the foregoing description that I have produced a unitary device of simple construction which may be manufactured, sold and installed as a unit at small expense.

The invention claimed is:

l. In combination with an enclosure and a movable closure member therefor having a rectangular-shaped opening therein, a unitary ventilator adapted to intert with said opening and to be installed therein as a unit and provided with flanges engaging the inner and outer surfaces of said closure member adjacent the side Walls and upper wall of said opening, a body comprising a box-like structure intertting with and enclosed by and fastened to said frame and consisting of spaced horizontally disposed track members having openings therein and inclined Walls meeting said track members to form walled inner and outer compartments with said track members having open inner and outer sides, slidable closure members engaging said track members and provided With openings adapted to register with the openings in said track members whereby air may flow from an outside source through the outer compartments, through 'the openings in said track members and slidable closure members and through said inner compartments and to the aforesaid enclosure and means for simultaneously operating said slidable closure members to open or close the openings in said track members.

2. A ventilator comprising a frame having flanges adapted to engage the inner and outer surfaces of a closure for a room, said closure being provided with a housing communicating with said ventilator, a body interfitting with and en closed by and fastened to said frame and consisting o track members having openings therein and integral with walls forming outer and inner compartments with said track members, closure members slidably engaging said track members and provided with openings adapted to be brought into registry with the openings in said track members, extensions secured to said closure members and projecting into said housing, means connecting said extensions together, operating means fastened to said means for slidably and simultaneously moving said slidable closure 1n embers on said track members to close, open, or partially open the openings in said track meinbers and shutters hingedly secured to the ventilator for closing the aforesaid inner compartments.

3. In combination with a closure having an opening and a slot therein, a housing communicating with said opening and slot, a ventilator frame interfitting with said opening, a ventilator body carried by said frame and provided with track members having openings therein and interior inclined Walls meeting said track members, slidable closure members engaging said track members and having openings therein adapted to be brought into registry with the openings in said track members, extensions on said slidable closure members extending Within said housing, means connecting said extensions together and outwardly projecting means connected to said connecting means and projecting through the aforesaid slot for simultaneously actuating said slidable closure members and thereby regulate the size of the openings in the aforesaid track members.
